UDaily: Microbe mobilizes 'iron shield' to block arsenic uptake in rice

University of Delaware researchers have discovered a soil microbe that mobilizes an “iron shield” to block the uptake of toxic arsenic in rice. 

Arsenic occurs naturally in rocks and soils, air and water, plants and animals. It’s used in a variety of industrial products and practices, from wood preservatives, pesticides and fertilizers, to copper smelting. Chronic exposure to arsenic has been linked to cancer, heart disease and diabetes.
